1. The _B __ __ __ __ __ __ __ __ is made up of the parts of the planet including
land,
water or atmosphere in which all life exists.
2. _N_ __ __ __ __ __ __ __ _F_ __ __ __ __ __ __ __ is the process in which nitrogen
gas from the atmosphere is converted into ammonia by bacteria that live in the soil and on the
roots of plants called legumes
3. The type of symbiosis in which both organisms benefit from living in close association is
called _M_ __ __ __ __ __ __ __ __.
4. Unlike carbon, hydrogen, and oxygen, _P_ __ __ __ __ __ __ __ __ __ , an element found
in DNA, does NOT enter the atmosphere as it cycles through the ecosystem.
5. A _P_ __ __ __ __ __ __ __ __ __ is a group of individuals that belong to the same
species and live in the same area.
6. _T_ __ __ __ __ __ __ __ __ __ __ __ __ ,the process in which water evaporates from the
surface of green plant leaves, is one way water molecules return to the atmosphere.
7. A group of organisms so similar to one another that they can breed and produce fertile
offspring = _S_ __ __ __ __ __ __
8. An _O_ __ __ __ __ __ __ __ eats both plants and animals.
9. A symbiotic relationship in which one member of the association benefits while the other is
neither helped nor harmed = _C_ __ __ __ __ __ __ __ __ __ __ __.
10. A _H_ __ __ __ __ __ __ __ __ obtains energy by eating only plants.
11. Type of interaction in which organisms fight to use a resource in the same place and at the
same time = _C_ __ __ __ __ __ __ __ __ __ __.
12. Another name for a CONSUMER = _H_ __ __ __ __ __ __ __ __ __ __.
13. An organism that eats only meat is called a _C_ __ __ __ __ __ __ __ __.
14. _E_ __ __ __ __ __ __ is the science that studies the interactions of organisms with each
other and with their environment.
15. Bacteria and _F_ __ __ __ __ are decomposers, an important group of heterotrophs that
break down organic matter.
16. Some bacteria use _C_ __ __ __ __ __ __ __ __ __ __ __ __ __, a process in which
energy from the chemical bonds of inorganic molecules is used to produce carbohydrates
in the absence of light.
17. An interaction in which one organism captures and feeds on another
= _P_ __ __ __ __ __ __ __ __
18. Atoms like carbon, nitrogen, and phosphorus are reused and passed throughout parts of the
biosphere in _B_ __ __ __ __ __ __ __ __ __ __ __ __ __
_C_ __ __ __ __ __.
19. An interaction in which one organism lives in a close association with another
= _S_ __ __ __ __ __ __ __ __.
20. A _P_ __ __ __ __ __ __ __ captures and eats a prey animal.
21. Type of symbiosis in which one organism benefits while the other is harmed.
= _P_ __ __ __ __ __ __ __ __ __
22. An organism’s _H_ __ __ __ __ __ __ or “address” describes the area where it lives.
23. Process in which energy from sunlight is used by green plants to convert carbon dioxide and
water into oxygen and carbohydrates = _P_ __ __ __ __ __ __ __ __ __ __ __ __ __
24. _D_ __ __ __ __ __ __ __ __ __ __ __ __ __ __ is the process in which soil bacteria
convert nitrates into nitrogen gas which is released into the atmosphere.
25. An organism’s “occupation” or _N_ __ __ __ __ includes all the physical and biological
conditions in which it lives.
26. All the different populations that live together in a certain area form a
= _C_ __ __ __ __ __ __ __ __
27. “Lunch” for a predator = _P_ __ __ __
28. Each step in food chain or food web is called a _T_ __ __ __ __ __ __ level.
29. Organisms that can make their own food are called _P_ __ __ __ __ __ __ __ __ or
AUTOTROPHS.
30. The network of complex interactions formed by linking together all the food chains in an
ecosystem = _F_ __ __ __
_W_ __ __.
31. All the organisms that live in a place together with their nonliving or physical environment
= _E_ __ __ __ __ __ __ __ __
32. _A_ __ __ __ __ __ __ factors are all the non-living factors that shape ecosystems such
as climate, precipitation, wind, nutrient availability, soil type, and sunlight.
33. A _L_ __ __ __ __ __ __ __ factor is a requirement that is in short supply or recycles
slowly to keep the population in check.
34. The _C_ __ __ __ __ __ __ __ __ __ __ _E_ __ __ __ __ __ __ __ __ Principle
states that no two species can occupy the same niche in the same habitat at the same time.
